Dr Mirriam Moleko, a lecturer in the Department of Mathematics, Natural Sciences, and Technology Education in the UFS Faculty of Education, participated in the National Research Foundation’s Black Academics Advancement Programme fellowship and got the opportunity to visit universities and schools in the USA for three weeks.

After completing the National Research Foundation’s Black Academics Advancement Programme (BAAP) fellowship, a lecturer from the University of the Free State (UFS) now wants to train more teachers on issues of access and inclusivity in different mathematics settings. She also wants to establish a centre for access and inclusivity to promote quality teaching that caters to a diverse learner population.

Dr Mirriam Moleko, a lecturer in the UFS’s Department of Mathematics, Natural Sciences, and Technology Education in the Faculty of Education, participated in the BAAP fellowship, an initiative of the National Research Foundation (NRF) and the FirstRand Foundation (FRF), from 2021 to 2022. She also got the opportunity to visit universities and schools in the USA for three weeks.

Supporting emerging academics

Dr Moleko says the BAAP is a prestigious NRF programme which supports well-structured research projects with achievable aims, sound methodologies, and demonstrated prudent use of funds. The programme supports emerging academics to ensure that they develop strong research skills, collaborate with prolific scholars in their fields, visit other universities abroad, give public lectures, and attend international conferences to establish an international footprint.

“The programme allows the candidates awarded the grant to focus on research for two years” she says. “I managed to run my teacher community research project successfully during this period. My goal as an academic and a researcher is to produce work that teachers can relate to and be able to apply in their profession. I have always aspired to empower teachers to be knowledgeable and resourceful”.

“Furthermore, my goal is to strive to partake in critical conversations that are taking place within the mathematics education field, and to contribute my skills and knowledge in addressing the existing challenges, thus being part of the solution. I believe the skills that I have gained on how to conduct quality research will assist me in achieving my goals,” she added.

Benefit from funding

During the period of her fellowship she learned about forming partnerships and collaborating with other scholars in her field, which she believes is an important skill to possess as a developing scholar.

Dr Moleko says the programme played a pivotal role in the attainment of numerous significant accomplishments in her professional career thus far. She also benefitted in terms of funding, which helped her undertake autonomous research and advanced training in her area of expertise, as well as facilitated engagement in collaborative research ventures with esteemed professionals and researchers, both domestically and abroad.

“The research leave that I got enabled me to successfully conceptualise, strategise, and implement a research endeavour that yielded a more profound comprehension of the research gap that I had identified within the teacher community, thus culminating in multiple publications in esteemed periodicals.

“The NRF-BAAP funding also enabled me to undertake training, thereby refining my skill set and augmenting my comprehension of intricate principles. The experience proved to be a crucial factor in my vocational growth and bolstered my aptitude for scholarly inquiry. It also afforded me the chance to engage in mentoring endeavours for fledgling researchers.”

Transformation of the Professoriate Mentoring Programme

Dr Moleko, who is part of the UFS Transformation of the Professoriate Mentoring Programme, says this programme is an excellent initiative which is aimed at preparing young academics for future promotions and offering them skills to be competitive. The programme’s goals include building strong academics who will follow in the footsteps of the university’s current leaders.

She says the programme is critical in supporting young academics by connecting them with seasoned mentors and scholars from various fields of study. It is essential for young academics in terms of maximising their learning, expanding their network, and gaining opportunities to help facilitate their growth.

“I see the programme as a catalyst for change necessary for the university to realise the desired results,” Dr Moleko says.

During her visit to the USA she spent two weeks at Boston College and the University of Rhode Island, and also visited the Center for Applied and Specialised Technology, the Paul V. Sherlock Center on Disabilities (Sherlock Center), and the TechACCESS Center.

“The purpose of my visit was to establish networks and collaborate with prolific scholars outside South Africa on research engagements. Furthermore, the visit was intended for me to meet with my international mentors in person regarding research engagements.

“During my research visit, Prof Elizabeth Dalton from Rhode Island University and a UDL specialist, and I focused on several academic conversations and demonstrations of Universal Design for Learning (UDL) strategies and approaches, as well as the sharing of many online resources available to support the implementation of UDL in inclusive settings.”

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
